The ServerFixture.LoadSdfModelRelativeUri test in UNIT_Server_Rendering_TEST.cc was failing because it contains a mesh uri pointing to a non-existent dae file. With SetStoreResolvedURIs set to true, it returns an error and so the server stops loading the model. This breaks current behavior. To resolve this, I added logic in ddf7f46 to allow the server to proceed with presence of URI_LOOKUP errors.

Looking for feedback on this. Any objections to allowing Server to continue loading with presence of URI errors?

I'm not sure this is a good idea. The URI_LOOKUP error is not just emitted for missing mesh files, but also when an included model is not found, which should be a blocker error IMO.

[iche033]

The other option is to not return the URI_LOOKUP error in sdformat when resolving URIs but that's also not ideal.

So with SetStoreResolvedURIs now set to true, we'll just be more strict and stop the Server from loading if an URI is not found. How does that sound?

[azeey]

Maybe we can define a parameter in ServerConfig that determines if a SDF errors prevent the Server from loading. Or it could be an environment variable. Either way, we can just set that in the test without affecting end users.

Added a new parameter in ServerConfig, blockOnSdfErrors to stop server from loading in presence of SDF errors. It can also be passed from the command line, gz sim -v 4 shapes.sdf --block-on-sdf-errors 1. fbddcb7

DCO needs to be fixed.
